Operation HARDTACK, Program 39 (Projects 39.1 and 39.2). Attenuation of Weapons Radiation: Application to Japanese Houses.

Abstract

Measurements were made of the radiation dose distributions in facsimiles of Japanese dwellings as a function of house size, orientation, and mutual shielding. Collimators were used in determining the angular distribution of neutrons and gamma rays incident on the point of measurement relative to a line between the point and the detonation. The relaxation length for fast neutrons measured for three nuclear detonations was 210, 218, and 205 yards, reduced to standard temperature and pressure. Criteria have been established to calculate the fast neutron dose distribution in Japanese houses for a given geometrical configuration and free space dose.
